Subject: btrfs: use the btrfs_space_info_free_bytes_may_use helper for delalloc
Git-commit: 39753e4a3a43c7d14a17f626f32d4a53ee59d563
Patch-mainline: v5.10-rc1
References: bsc#1135481

We are going to use the ticket infrastructure for data, so use the
btrfs_space_info_free_bytes_may_use() helper in
btrfs_free_reserved_data_space_noquota() so we get the
btrfs_try_granting_tickets call when we free our reservation.
